Vitamin B2 is defined by more than its assay range; its quality control also accounts for sensitivity to light. At 440 nm, the lumiflavin limit is no more than 0.025, which helps monitor an absorbance indicator associated with degradation. As a result, storage and formulation require protection from light.

A specific rotation of −115° to −135° serves as an identity specification alongside the positive identification test. Low loss on drying and residue on ignition help preserve powder quality in dry blends, premixes, tablets, capsules, and fortified food applications.
