羟基频哪酮视黄酸酯分子式是什么?HPR分子式、分子量及CAS号详解

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

如果您正在查询“羟基频哪酮视黄酸酯分子式”,最需要确认的一点是:C26H38O3 指的是羟基频哪酮视黄酸酯这一化合物本身的分子式。市场上的 HPR 10%溶液、包裹型HPR或其他复配型原料可能还含有溶剂、载体等其他成分,因此不能直接把复配产品整体都理解为 C26H38O3。

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

一、羟基频哪酮视黄酸酯分子式是什么?

羟基频哪酮视黄酸酯的化学分子式是:

C26H38O3

这个分子式表示一个羟基频哪酮视黄酸酯分子由26个碳原子、38个氢原子和3个氧原子组成。

从采购、研发或者原料资料核对的角度来看,分子式通常需要与CAS号一起核对。羟基频哪酮视黄酸酯常见CAS号为893412-73-2。如果供应商资料中的产品名称、CAS号和分子式无法对应,建议进一步查看COA、SDS、TDS、HPLC或其他检测资料,而不要只根据中文商品名称判断。

二、HPR分子量是多少?

按照 C26H38O3 的元素组成计算,羟基频哪酮视黄酸酯的相对分子质量约为398.58,因此常见资料中通常标注:

Molecular Weight:398.58 g/mol

部分数据库会按照显示精度写成398.6 g/mol,这属于小数位数不同,并不表示是不同物质。

三、羟基频哪酮视黄酸酯分子式和结构式有什么区别?

在查询HPR资料时,经常会同时看到“分子式”和“结构式”,两者并不是同一个概念。

分子式 C26H38O3主要说明HPR中碳、氢、氧三种元素及其原子数量;而结构式则进一步表示这些原子之间如何连接,可以反映分子中的官能团以及整体化学结构。

因此,如果只是确认原料身份或填写产品基础参数,通常使用分子式即可;如果涉及化学结构研究、原料鉴定或进一步的技术分析,则还需要结合结构式、SMILES、InChI、NMR等资料。

四、为什么HPR的分子式是C26H38O3?

羟基频哪酮视黄酸酯属于视黄酸相关的酯类化合物。公开化学数据库中可以查询到其系统化学名称以及对应结构信息,其分子组成最终可以归纳为26个碳原子、38个氢原子和3个氧原子,因此分子式写作C26H38O3。

对于实际采购人员来说,没有必要只通过名称自行推算分子式,更可靠的方法是同时核对CAS 893412-73-2、英文名称 Hydroxypinacolone Retinoate以及分子式 C26H38O3。

五、纯HPR与HPR 10%溶液的分子式一样吗?

这是采购和配方人员比较容易混淆的问题。

纯羟基频哪酮视黄酸酯本身的分子式为C26H38O3。

但是市场上还存在HPR 10%溶液、油溶型HPR、包裹型HPR等商品形式。这类产品可能由HPR与溶剂、载体或其他辅料组成,因此它们属于混合体系,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:

  • 产品名称:羟基频哪酮视黄酸酯 / Hydroxypinacolone Retinoate

  • 简称:HPR

  • CAS号:893412-73-2

  • 分子式:C26H38O3

  • 分子量:约398.58 g/mol

  • 产品含量:确认是高含量HPR原料还是HPR复配溶液

  • 检测方法:根据供应商资料核对HPLC等检测信息

  • 批次资料:查看COA、SDS、TDS等文件

对于大货采购,尤其需要区分“化学物质本身的基础参数”和“供应商实际交付产品的规格参数”。前者可以通过权威数据库核对,后者则应以具体批次的检测报告和产品规格书为准。

七、羟基频哪酮视黄酸酯分子式常见问题

1. 羟基频哪酮视黄酸酯分子式是多少?

羟基频哪酮视黄酸酯(Hydroxypinacolone Retinoate,HPR)的分子式为C26H38O3。

2. HPR的CAS号是多少?

常见CAS号为893412-73-2。

3. 羟基频哪酮视黄酸酯分子量是多少?

分子量约为398.58 g/mol,部分数据库按照小数位数会显示为398.6 g/mol。

4. HPR 10%的分子式也是C26H38O3吗?

C26H38O3是Hydroxypinacolone Retinoate这一化合物自身的分子式。HPR 10%商品通常还含有溶剂或其他载体,因此整个商品属于混合物,不能简单用C26H38O3表示全部组成。

5. 羟基频哪酮视黄酸酯和HPR是同一种原料吗?

在化妆品原料和相关技术资料中,HPR通常是Hydroxypinacolone Retinoate的简称,即羟基频哪酮视黄酸酯。采购时仍建议结合CAS号893412-73-2进行确认。

总结

羟基频哪酮视黄酸酯的分子式为C26H38O3,英文名称为Hydroxypinacolone Retinoate,常简称为HPR,CAS号为893412-73-2,分子量约为398.58 g/mol。

对于原料采购和配方研发人员来说,查询分子式只是确认产品身份的第一步。实际采购时还应进一步核对产品含量、检测方法以及COA、SDS、TDS等批次和技术资料,尤其要注意区分纯HPR原料与HPR 10%等复配型产品。
