Chemical Structure

(R)-2,7,8-Trimethyl-2-((3E,7E,11E,15E,19E,23E,27E)-4,8,12,16,20,24,28,32-octamethyltritriaconta-3,7,11,15,19,23,27,31-octaen-1-yl)chroman-6-ol CAS 4382-43-8 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (R)-2,7,8-Trimethyl-2-((3E,7E,11E,15E,19E,23E,27E)-4,8,12,16,20,24,28,32-octamethyltritriaconta-3,7,11,15,19,23,27,31-octaen-1-yl)chroman-6-ol is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 751.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies (R)-2,7,8-Trimethyl-2-((3E,7E,11E,15E,19E,23E,27E)-4,8,12,16,20,24,28,32-octamethyltritriaconta-3,7,11,15,19,23,27,31-octaen-1-yl)chroman-6-ol (CAS 4382-43-8), a certified reference material (molecular formula C53H82O2, MW 751.22 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
