羟基频哪酮视黄酸酯结构式是什么?HPR分子结构、分子式及CAS号详解

羟基频哪酮视黄酸酯结构式是很多化妆品研发人员、原料采购人员在了解HPR(Hydroxypinacolone Retinoate)时首先需要确认的信息。羟基频哪酮视黄酸酯是一种视黄酸酯类化合物,CAS号为893412-73-2,分子式为C26H38O3,相对分子质量约为398.58。

从分子结构来看,羟基频哪酮视黄酸酯保留了典型的维A类共轭多烯结构,同时视黄酸末端的羧基经过酯化形成了新的酯基结构。本文将围绕羟基频哪酮视黄酸酯结构式、分子式、结构特点、SMILES以及实际原料识别方法进行说明。

一、羟基频哪酮视黄酸酯结构式基本信息

中文名称羟基频哪酮视黄酸酯
英文名称Hydroxypinacolone Retinoate
常用简称HPR
CAS号893412-73-2
分子式C26H38O3
分子量约398.58 g/mol
PubChem CID25054592
InChIKeyXLPLFRLIWKRQFT-XUJYDZMUSA-N

需要注意的是,结构式和分子式并不是同一个概念。C26H38O3只是表示一个羟基频哪酮视黄酸酯分子中含有26个碳原子、38个氢原子和3个氧原子,而结构式进一步表示这些原子之间具体如何连接。

二、羟基频哪酮视黄酸酯的结构有什么特点?

从羟基频哪酮视黄酸酯结构式可以看出,其分子并不是一个简单的短链酯类,而是具有比较明显的维A类化合物结构特征。

1、具有典型的维A类共轭多烯结构

HPR分子中存在连续的不饱和碳链和多个共轭双键,这也是Retinoid类化合物结构上的重要特征之一。

其结构一端包含带有甲基取代的环己烯结构,之后连接较长的共轭多烯链,再连接酯基和含羰基的支链结构。

2、属于视黄酸的酯类衍生物

从化学结构角度看,Hydroxypinacolone Retinoate可以表示为视黄酸形成的一种酯类衍生物。

其系统名称之一为:

(3,3-dimethyl-2-oxobutyl) (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoate

这个名称虽然比较长,但其中已经描述了HPR分子中双键位置、取代基以及酯结构等重要信息。

3、分子中含有3个氧原子

羟基频哪酮视黄酸酯的分子式是C26H38O3,其中的3个氧原子主要来自酯基和羰基相关结构。

因此,通过HPR结构式不仅可以看到维A类共轭骨架,也可以直接观察到与普通视黄醇结构不同的酯化部分。

三、羟基频哪酮视黄酸酯SMILES结构表达式

除了常见的二维化学结构图以外,在化学数据库、原料数据库和科研资料中还经常使用SMILES来表示化合物结构。

PubChem收录的羟基频哪酮视黄酸酯结构可以用以下SMILES表示:

CC1=C(C(CCC1)(C)C)/C=C/C(=C/C=C/C(=C/C(=O)OCC(=O)C(C)(C)C)/C)/C

SMILES是一种将分子结构转换为文本字符的方法,主要用于化学数据库检索、结构搜索以及化学信息软件中的分子识别。

对于普通化妆品原料采购而言,并不需要记住完整SMILES,但是如果需要核对供应商提供的结构资料、CAS信息或者第三方检测资料,SMILES、InChIKey和CAS号可以作为辅助识别信息。

四、羟基频哪酮视黄酸酯结构式和分子式有什么区别?

在搜索“羟基频哪酮视黄酸酯结构式”时,经常会同时看到C26H38O3,因此容易把两者混在一起。

实际上:

分子式:C26H38O3

它只能说明HPR分子中各种元素的数量。

结构式:则显示26个碳原子、38个氢原子和3个氧原子之间具体采用什么方式连接,同时可以显示双键、酯键、羰基以及环状结构等信息。

因此,在判断一种物质是不是羟基频哪酮视黄酸酯时,仅仅看到C26H38O3还不够,更严谨的方法是同时核对CAS号、结构式、分子式、分子量以及分析检测数据。

五、羟基频哪酮视黄酸酯为什么属于Retinoid类结构?

HPR的结构中包含Retinoid类化合物具有代表性的环状末端以及共轭多烯链结构。

从结构来源上看,它可以理解为视黄酸的酯类衍生物,因此在英文资料中除了Hydroxypinacolone Retinoate之外,也可以看到Retinoic acid, 3,3-dimethyl-2-oxobutyl ester这一名称。

FDA GSRS等数据库也将CAS 893412-73-2对应到Hydroxypinacolone Retinoate,并记录其分子式为C26H38O3。

六、如何通过结构信息确认是不是羟基频哪酮视黄酸酯?

如果是化妆品企业进行HPR原料采购,建议不要只根据产品名称判断,可以重点检查以下几个信息。

1、核对CAS号

羟基频哪酮视黄酸酯常用CAS号为:

893412-73-2

2、核对分子式

对应分子式应为:

C26H38O3

3、核对分子量

公开化学数据库中记录的相对分子质量约为:

398.58~398.6 g/mol

4、查看COA和检测资料

对于原料采购,仅核对结构式还不能替代实际质量检测。采购时还应结合供应商提供的COA、HPLC检测结果以及必要的结构表征资料进行判断。

如果采购的是高纯度HPR粉末,还可以进一步要求供应商提供批次检测报告以及必要的NMR、HPLC等检测资料,用于确认原料身份和纯度。

七、羟基频哪酮视黄酸酯结构式常见问题

羟基频哪酮视黄酸酯的分子式是什么?

羟基频哪酮视黄酸酯的分子式为C26H38O3。

羟基频哪酮视黄酸酯分子量是多少?

其分子量约为398.58 g/mol,不同数据库的小数位显示可能略有差异,例如398.58、398.59或398.6,这通常来自计算和保留位数不同。

羟基频哪酮视黄酸酯CAS号是多少?

Hydroxypinacolone Retinoate对应CAS号为893412-73-2。

HPR就是羟基频哪酮视黄酸酯吗?

在化妆品原料和相关技术资料中,HPR通常作为Hydroxypinacolone Retinoate的简称,即羟基频哪酮视黄酸酯。

羟基频哪酮视黄酸酯结构式和视黄醇一样吗?

不一样。虽然两者都属于维A相关化合物,并具有部分相似的Retinoid骨架特征,但羟基频哪酮视黄酸酯具有不同的末端官能团和酯类结构,因此其分子式、分子量以及完整化学结构均不同于Retinol。

八、总结

羟基频哪酮视黄酸酯(Hydroxypinacolone Retinoate,HPR)的CAS号为893412-73-2,分子式为C26H38O3,分子量约为398.58 g/mol。

从羟基频哪酮视黄酸酯结构式可以看到,其分子包含典型的Retinoid共轭多烯结构,同时具有酯基和羰基相关结构。对于研发或采购人员而言,结构式能够帮助理解HPR的化学身份,但在实际原料采购和质量判断过程中,还应同时核对CAS号、COA、HPLC以及必要的NMR等检测资料。

因此,在查询“羟基频哪酮视黄酸酯结构式”时,建议不要只看单一的结构图片,而应将结构式、CAS号、分子式、分子量和检测资料结合起来进行判断。
