Ibrahim, S. A. published the artcileColorimetric method for the estimation of antazoline, Application of N-Benzyl-N-((4,5-dihydro-1H-imidazol-2-yl)methyl)aniline hydrochloride, the publication is Indian Journal of Pharmacy (1974), 36(3), 73-5, database is CAplus.

A sensitive colorimetric method was developed for the determination of antazoline-HCl (I) [2508-72-7] in the pure state and in pharmaceutical preparations It depends on estimating the color produced when I was treated with nitrite. Thus, a 20 ml aliquot of I solution (stock solution contains 0.5% I-HCl in water) was treated with 4 ml NaNO2 solution (7.5% in concentrated H2SO4) 5 min at room temperature, and the solution was diluted to 50 ml with 15% aqueous AcONa. Absorbance was read within 10 min at 416 nm against a reagent blank. Data were given on the estimation of I by this method in pharmaceutical formulations. No interference was produced by phenylephrine-HCl [61-76-7], ephedrine-HCl [50-98-6], naphazoline-HCl [550-99-2], chlorobutanol [57-15-8], benzalkonium chloride, or polyethylene glycol [25322-68-3].

Hydrophilic matrix tablets containing antazoline-HCl (I) [2508-72-7] were prepared by incorporation of hydroxpropyl Me cellulose  [9004-65-3]. Thus, double-layer tablets were obtained containing both the drug with an extended releasing rate (incorporated in the hydrophilic matrix) and the same drug with normal releasing rate. The release rate of I from these tablets was estimated by the half-exchange method.

One of the granulates used and one of the layers in the resulting tablets contained a hydrophobic matrix comprising poly(vinyl chloride). Two doses of the active substance were used as well as various excipients and various proportions of distribution of the active substance between the particular granulates or layers. The rate of in vitro release of antazoline-HCl from these tablets was estimated by the half-exchange method into artificial gastric and intestinal juices.

A simple and rapid anal. procedure for routine quantification of n-C₁₂H₂₅ and n-C₁₄H₂₉ benzalkonium chloride (C-12 and C-14 BKC) homologs in ophthalmic formulations containing antazoline HCl and tetrahydrozoline HCl by high-performance liquid chromatog. was developed and validated. The ophthalmic solution samples can be directly analyzed by reversed-phase on HiQ-Sil C18 column (4.6 mm × 150 mm, i.d., 5-μm particle size) with acetonitrile-sodium acetate buffer (pH 5.0; 0.2 M) (70:30, volume/volume) as mobile phase. UV Detection was carried out at 262 nm. The method was linear over the selected concentration and ranged from 0.03 to 0.10 mg/mL (r² = 0.9999) and from 0.01 to 0.05 mg/mL (r² = 0.9979) for C-12 and C-14 BKC homologs, resp. The mean percent recoveries were 100.2 and 102.6 and the percent CV values were 1.3 and 3.5 for C-12 and C-14 BKC homologs, resp. The results demonstrated the good linearity, accuracy, and precision. The method was applied to determine 2 com. ophthalmic formulations, and the percent label amounts of total BKC contents were found to be 99.7 and 103.2.
