Chemical Structure

4-Nitro-tetrahydro-2H-pyran CAS 1313738-95-2 chemical structure

Description

4-Nitro-tetrahydro-2H-pyran (CAS 1313738-95-2), molecular formula C5H9NO3 and molecular weight 131.13 g/mol, is a CATO reference standard with documented purity and traceability.

4-Nitro-tetrahydro-2H-pyran (C5H9NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.

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), 4-Nitro-tetrahydro-2H-pyran 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.
