Wat is die molekulêre formule van hidroksipinakoloon-retinoaat? HPR molekulêre formule, molekulêre massa en CAS-nommer verduidelik

Hidroksipinakoloon-retinoaat (Hydroxypinacolone Retinoate, afgekort HPR) se
molekulêre formule is C26H38O3
,CAS-nommer is
893412-73-2,molekulêre massa is ongeveer
398.58 g/mol
。

As u navraag doen oor "hidroksipinakoloon-retinoaat molekulêre formule", is die belangrikste punt om te bevestig:
C26H38O3 verwys na die molekulêre formule van die hidroksipinakoloon-retinoaat-verbinding self
。HPR 10%-oplossings, ingekapsuleerde HPR of ander saamgestelde grondstowwe op die mark kan ook oplosmiddels, draers en ander bestanddele bevat, daarom kan die saamgestelde produk as geheel nie direk as C26H38O3 verstaan word nie.

Hidroksipinakoloon-retinoaat molekulêre formule(Beeld1)

1. Wat is die molekulêre formule van hidroksipinakoloon-retinoaat?

Die chemiese molekulêre formule van hidroksipinakoloon-retinoaat is:

C26H38O3

Hierdie molekulêre formule toon dat een hidroksipinakoloon-retinoaat-molekuul bestaan uit
26 koolstofatome, 38 waterstofatome en 3 suurstofatome
saamgestel.

Vanuit die perspektief van verkryging, navorsing en ontwikkeling of die nasien van grondstofinligting, moet die molekulêre formule gewoonlik saam met die CAS-nommer nagegaan word. Die algemene CAS-nommer van hidroksipinakoloon-retinoaat is
893412-73-2As die produknaam, CAS-nommer en molekulêre formule in die verskaffer se inligting nie ooreenstem nie, word dit aanbeveel om COA, SDS, TDS, HPLC of ander toetsinligting verder na te gaan, eerder as om slegs op die Chinese handelsnaam te oordeel.

2. Wat is die molekulêre gewig van HPR?

Volgens die elementêre samestelling C26H38O3 bereken, is die relatiewe molekulêre massa van hidroksipinakoloon-retinoaat ongeveer
398.58, daarom word dit gewoonlik in algemene bronne aangedui as:

Molekulêre massa: 398.58 g/mol

Sommige databasisse skryf dit as 398.6 g/mol volgens vertoonpresisie, wat slegs 'n verskil in desimale plekke is en nie beteken dit is 'n ander stof nie.

Drie: Wat is die verskil tussen die molekulêre formule en die struktuurformule van hidroksipinakoloon-retinoaat?

Wanneer 'HPR'-inligting nageslaan word, sien mens dikwels beide "molekulêre formule" en "struktuurformule", maar dit is nie dieselfde begrip nie.

Molekulêre formule C26H38O3
verduidelik hoofsaaklik die drie elemente koolstof, waterstof en suurstof in HPR en hul atoomgetalle; terwyl
struktuurformule
verder aandui hoe hierdie atome met mekaar verbind is, wat die funksionele groepe en die algehele chemiese struktuur van die molekule kan weerspieël.

Dus, as dit slegs gaan oor die bevestiging van die identiteit van die grondstof of die invul van basiese produkparameters, is die molekulêre formule gewoonlik voldoende; as dit egter chemiese struktuurstudies, grondstofidentifikasie of verdere tegniese analise behels, is dit nodig om ook struktuurformules, SMILES, InChI, NMR en ander inligting te gebruik.

Vier, waarom is die molekulêre formule van HPR C26H38O3?

Hidroksipinakoloon-retinoaat behoort aan retinoïensuurverwante esterverbindings. Die sistematiese chemiese naam en ooreenstemmende struktuurinligting kan in openbare chemiese databasisse nageslaan word, en die molekulêre samestelling kan uiteindelik saamgevat word as 26 koolstofatome, 38 waterstofatome en 3 suurstofatome, dus word die molekulêre formule geskryf as
C26H38O3
。

Vir werklike aankopers is dit nie nodig om die molekulêre formule slegs op grond van die naam self af te lei nie; 'n meer betroubare metode is om gelyktydig te verifieer
CAS 893412-73-2, Engelse naam Hydroxypinacolone Retinoate en molekulêre formule C26H38O3
。

Vyf, is die molekulêre formule van suiwer HPR en HPR 10%-oplossing dieselfde?

Dit is 'n kwessie wat maklik deur aankopers en formuleerders verwar word.

Die molekulêre formule van suiwer hidroksipinakoloon-retinoaat self is C26H38O3.

Maar daar bestaan ook kommersiële vorms soos HPR 10%-oplossing, olie-oplosbare HPR, ingekapselde HPR, ens. Hierdie tipe produkte kan uit HPR en oplosmiddels, draers of ander hulpstowwe bestaan, daarom behoort hulle aan
gemengde stelsels
,不能用一个C26H38O3代表整个商品的全部组成。

例如,一款标称“HPR 10%”的原料,其“10%”通常描述的是产品中HPR的含量,而不是说HPR本身的分子式发生了变化。

六、查询HPR分子式时还应该同时确认哪些参数?

如果查询“羟基频哪酮视黄酸酯分子式”的目的是采购原料或者进行配方开发,建议不要只确认C26H38O3,还可以同时核对以下信息:

  • Produknaam:
    Hidroksipinakoloon Retinoaat / Hydroxypinacolone Retinoate

  • Afkorting:
    HPR

  • CAS-nommer:
    893412-73-2

  • Molekulêre formule:
    C26H38O3

  • Molekulêre massa:
    Omtrent 398.58 g/mol

  • Produk inhoud:
    Bevestig of dit hoë-konsentrasie HPR-grondstof of HPR-saamgestelde oplossing is

  • Toetsmetode:
    Verifieer HPLC- en ander toetsinligting volgens verskafferdata

  • Lotdata:
    Bekyk COA-, SDS-, TDS- en ander dokumente

Vir grootmaat-aankope is dit veral nodig om te onderskei tussen "die basiese parameters van die chemiese stof self" en "die spesifikasies van die produk wat die verskaffer werklik lewer". Eersgenoemde kan deur gesaghebbende databasisse geverifieer word, terwyl laasgenoemde op die toetsverslae en produkspesifikasies van die spesifieke lot gebaseer moet word.

7. Algemene vrae oor die molekulêre formule van hidroksipinakoloon-retinoaat

1. Wat is die molekulêre formule van hidroksipinakoloon-retinoaat?

Die molekulêre formule van hidroksipinakoloon-retinoaat (Hydroxypinacolone Retinoate, HPR) is
C26H38O3
。

2. Wat is die CAS-nommer van HPR?

Die algemene CAS-nommer is
893412-73-2。

3. Wat is die molekulêre massa van hidroksipinakoloon-retinoaat?

Die molekulêre massa is ongeveer
398.58 g/mol
,Sommige databasisse sal dit as 398.6 g/mol vertoon, afhangende van die aantal desimale plekke.

4. Is die molekulêre formule van 10% HPR ook C26H38O3?

C26H38O3 is
die molekulêre formule van die verbinding Hydroxypinacolone Retinoate self
。10% HPR-produkte bevat gewoonlik ook oplosmiddels of ander draers, daarom is die hele produk 'n mengsel en kan C26H38O3 nie eenvoudig gebruik word om die volle samestelling voor te stel nie.

5. Is hidroksipinakoloon-retinoaat en HPR dieselfde grondstof?

In kosmetiese grondstof- en verwante tegniese dokumente is HPR gewoonlik die afkorting vir Hydroxypinacolone Retinoate, dit wil sê hidroksipinakoloon-retinoaat. By aankope word dit steeds aanbeveel om dit saam met CAS-nommer 893412-73-2 te bevestig.

Opsomming

Hidroksipinakoloon-retinoaat se
molekulêre formule is C26H38O3
,die Engelse naam is
Hydroxypinacolone Retinoate
,dikwels afgekort as
HPR
,CAS-nommer is
893412-73-2,molekulêre massa is ongeveer
398.58 g/mol
。

Vir grondstofaankopers en formule-ontwikkelaars is die naslaan van die molekulêre formule slegs die eerste stap om die produk se identiteit te bevestig. By werklike aankope moet die produk se inhoud, toetsmetodes sowel as lot- en tegniese dokumente soos COA, SDS en TDS verder nagegaan word, en daar moet veral gelet word op die onderskeid tussen
suiwer HPR-grondstof
en
saamgestelde produkte soos HPR 10%
。
