Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 51978-15-5 159QMY41RL 2-(Methacryloyloxy)ethyl hydrogen maleate (2-((2-Methyl-1-oxoallyl)oxy)ethyl) hydrogen maleate 2-Butenedioic acid (2Z)-, 1-(2-((2-methyl-1-oxo-2-propen-1-yl)oxy)ethyl) ester 2-Butenedioic acid (2Z)-, mono(2-((2-methyl-1-oxo-2-propenyl)oxy)ethyl) ester EINECS 257-569-5 UNII-159QMY41RL.

51978-15-5 159QMY41RL 2-(Methacryloyloxy)ethyl hydrogen maleate (2-((2-Methyl-1-oxoallyl)oxy)ethyl) hydrogen maleate 2-Butenedioic acid (2Z)-, 1-(2-((2-methyl-1-oxo-2-propen-1-yl)oxy)ethyl) ester 2-Butenedioic acid (2Z)-, mono(2-((2-methyl-1-oxo-2-propenyl)oxy)ethyl) ester EINECS 257-569-5 UNII-159QMY41RL (CAS 51978-15-5), molecular formula C10H12O6 and molecular weight 228.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H12O6, 51978-15-5 159QMY41RL 2-(Methacryloyloxy)ethyl hydrogen maleate (2-((2-Methyl-1-oxoallyl)oxy)ethyl) hydrogen maleate 2-Butenedioic acid (2Z)-, 1-(2-((2-methyl-1-oxo-2-propen-1-yl)oxy)ethyl) ester 2-Butenedioic acid (2Z)-, mono(2-((2-methyl-1-oxo-2-propenyl)oxy)ethyl) ester EINECS 257-569-5 UNII-159QMY41RL contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 228.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 51978-15-5 159QMY41RL 2-(Methacryloyloxy)ethyl hydrogen maleate (2-((2-Methyl-1-oxoallyl)oxy)ethyl) hydrogen maleate 2-Butenedioic acid (2Z)-, 1-(2-((2-methyl-1-oxo-2-propen-1-yl)oxy)ethyl) ester 2-Butenedioic acid (2Z)-, mono(2-((2-methyl-1-oxo-2-propenyl)oxy)ethyl) ester EINECS 257-569-5 UNII-159QMY41RL meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
