Additional information

The results from different experimental studies for calculation of density of N-(4-{bis[4-(dimethylamino)phenyl]methylene} cyclohexa-2,5- dien-1-ylidene)- N-methylmethanaminium chloride were summarized as follows:

According to first study density of N-(4-{bis[4-(dimethylamino)phenyl]methylene}cyclohexa-2,5- dien-1-ylidene)-N-methylmethanaminium chloride was determined by using CPSL/PTM/11 based on USP 1/2.

Based on obtained results the bulk density and tap density of N-(4-{bis[4-(dimethylamino)phenyl]methylene}cyclohexa-2,5- dien-1-ylidene)- N-methylmethanaminium chloride was determined as 0.471 g/cm³ and 0.684 g/cm³ respectively.

Other supporting study from authoritative database gestis determined the density of N-(4-{bis[4-(dimethylamino)phenyl]methylene} cyclohexa-2,5- dien-1-ylidene)-N-methylmethanaminium chloride as 1.19 g/cm³ at 20 deg C .
