Table 1 Analytical data for AT1S and AT2S

From: [¹¹¹In-DOTA]Somatostatin-14 analogs as potential pansomatostatin-like radiotracers - first results of a preclinical study

Analog	Purity	Expected MW (*m/z*)	ES-MS	System A^a t _R(min)	System B^b t _R(min)
AT1S	98%	2024.29	-	36.9	41.9
		[M + H⁺] = 2025.29
		[M + 2 H⁺] / 2 = 1013.14	-
		[M + 3 H⁺] / 3 = 675.76	675.60 (100)^*
AT2S	90%	2024.29		35.8	39.3
		[M + H⁺] = 2025.29
		[M + 2 H⁺] / 2 = 1013.14	1012.66 (60)^*
		[M + 3 H⁺] / 3 = 675.76	675.72 (40)^*

^aSystem A and ^bsystem B are described in the ‘Methods’ section. ^*Numbers in parenthesis signify relative intensities of peaks in the MS-spectra. MW, molecular weight.
