Chemical Structure

Methane-d2 (gas) CAS 676-55-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methane-d2 (gas).

Methane-d2 (gas) (CAS 676-55-1) is a high-purity analytical reference standard with the molecular formula CH2D2 and a molecular weight of 18.05 g/mol.

Structurally, Methane-d2 (gas) (CH2D2) contains deuterium isotope labeling. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 18.05 g/mol, it falls into the low-molecular-weight range.

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), Methane-d2 (gas) 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.
