Grigorovich took the found folios to Kazan', and after his death in 1876 the Codex was transferred to Russian State Library in Moscow where it carries the catalog number грнг 6 (M.1689).

Croatian diplomat and amateur scholar Antun Mihanović acquired 2 folios (containing Matthew 5.23 - 6.16) some time before Grigorovich made his discovery, and sent it to renowned Slovene Slavist Franz Miklosich, who had them published in 1850.

Text of Codex especially abounds with the usage of asigmatic aorist, and very frequent is the assimilation of vowels in compound adjectival declension and present forms (-aago, -uumu instead of -aego, -uemu; -aatъ instead of -aetъ etc.).

[3] Later researchers as Josip Hamm has warned that vocalization of yers (ъ > o, ь > e), as well as the occasional disappearance of epenthetic l, suggests Macedonian provenience.

Codex forms the base text for the contemporary rendition of the New Testament on the basis of the Slavic recensions in the series Novum Testamentum Palaeoslovenice.
