Description

I765I75FT2 HNX7574GTX JM7UH9Q3YN S5DPG6K67I 25805-17-8 Polyethyloxazoline Oxazole, 2-ethyl-4,5-dihydro-, homopolymer 2-Ethyl-4,5-dihydrooxazole, homopolymer UNII-I765I75FT2 UNII-HNX7574GTX UNII-JM7UH9Q3YN UNII-S5DPG6K67I (C5H9NO) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies I765I75FT2 HNX7574GTX JM7UH9Q3YN S5DPG6K67I 25805-17-8 Polyethyloxazoline Oxazole, 2-ethyl-4,5-dihydro-, homopolymer 2-Ethyl-4,5-dihydrooxazole, homopolymer UNII-I765I75FT2 UNII-HNX7574GTX UNII-JM7UH9Q3YN UNII-S5DPG6K67I (CAS 25805-17-8), a certified reference material (molecular formula C5H9NO, MW 99.13 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.
